' To all whom'it may concern:

Another object of the invention is to pro vide a gravity operated pi ewrench 1n com,

bination with a separab e spring pressed plunger whereby the device maybe changed into a spring actuated wrench.

With the aboveand other objects in View I have invented the wrenchillustrated in the accompanying drawings in which- Figure 1 is a sideelevation of my improved wrench having a. spring actuated means thereon,Fig. 21s a longitudinal sectional view of Fig. 1, Fig. 3 is an upperedge view thereof, Fig. 4 is an elevational. view showing the springactuated member removed, Fig. 5 is an elevational view of a housing fora spring operated plunger, and Fig. 6 is an end elevational viewthereof.

Like reference characters indicate like parts throughout thespecification and ,in

the several views in the drawings in which 1 is a shank having an'integral jaw. 2 thereon, said jaw being slotted to provide a recess 3therein to receive the neck 4 of the pivoted jaw 5, said jaw 5 beingpivoted in said slot 3 by means of the bolt 6. The neck 6 is providedwith an offset 7 having a channel 8 around said portion 7, said channelbeing adapted to receive the end 9 of a plunger 10 which is providedwith a reduced portion 11 to receive the spring 12 which is seated inthe enlarged bore 13 of the housing 14; Said bore isprovided with areduced portion 15 which forms a shoulder 16 against which the end 17 ofthe spring 12 is adapted to seat. The other end 18 of said spring isadapted to abut the shoulder 19 formed by the enlarged por-j tion of theplunger 10 whereby said spring is adapted to normally force said plungerraised as'shown in Fig. 1 the end 9 of the plunger 10 seats upon theportion 20 and holds said jaw in a raised position as shown in-Fig. 1. v

The shank 1 is provided ,witha pair-of pins 2l'and 22 which are adaptedto enter therecesses 23 and 24 of the housing 14 whereby bayonet jointsare formed to hold said housing on to said shank. The spring.

pressed plunger engaging the-neck 4 of the jaw 5 holds the housing inplace. When it is desired to. remove the housing from the all that isnecessary to do is to grasp the same with the hand and fQI'Ce itslightly forward, so that the vertical portion 0 the slot 23 will comein line with the pin 21 when the housing may. readily be removed, saidhousing being provided with depending portions 25 and 26 which areadapted to straddle the shank of the wrench, the slots 23 and 24 beingshown in the depending portion 26.

For certain work such for instance as where the wrench. is held above apipe it is desired to grasp, it may be used altogether without themember 14, the weight of the jaw causing it to bear against the pipeuntil a grip is had thereon. However, when it becomes necessary to usethe wrench from the under side of the pipe the wrench cannot be usedwithout the member 14 to force the jaw 5 against the pipe. 7

Havingnow describedmy invention that which I claim to be new and desireto procure by Letters Patent is:

1. In combination with a pipe wrench having a fixed and a pivoted jawand a shank, a separablespring actuated plunger member, adapted toactuate said pivoted jaw, a removable housing for said plunger member, abayonet lock connection between said housing and shank, a heel on saidpivoted jaw, against which said plunger is pressed to actuate the jawand hold said housing against accidental removal from said shank. 2.A'pipe wrench consisting of a shank having a fixed jaw thereon, apivoted jaw, a heel on said last jaw, a removable housing on said shank,a spring pressed lunger seated in said housing and adapted toengage saidheel to hold said pivoted jaw in either an'opened or closed position.

3. A pipe wrench consisting of a shank having a fixed jaw thereon, apivoted jaw, a heel on' said last jaw, a removable housing on saidshank,a spring pressed plunger housing havingopposing depending side wallslots in said walls and pins on said shank, the action of said plungeragainst said heel adapted to hold said iins'and slots interlocked.

4. In combination with a' pipe wrench having a shank with an integraljaw-and a pivoted jaw, a removable plunger seated outwardly of saidshank and adapted to control said last jaw, a spring adaptedto actuatesaid plunger, a housing for said plunger and spring, said 'housing beingre- ,movably secured to the outer walls of said shank, slots in saidhousing and pins 'on said shank whereby they are connected.

5. In combination with a pipe wrench having a shank with an integral jawand a pivoted aw, a removable plunger seated outwvardly of said shankand adapted to con- 7 trol said last jaw, a spring adapted to actuatesaid plunger, a housing for said plunger and spring, said housing beingremovah] y secured to the outer walls of said shank, slots in saidhousing and pins on said shank whereby they are connected, said plungeradapted to press against said pivoted jaw and thereby hold said housingagainst accidental removal from said shank.

In testimony whereof I afiix my signature in presence of two witnesses.
